To support the growth of Ka-Band satellites for commercial and military applications, DiTom Microwave has developed a space-qualified isolator for use in the input multiplexer or similar low power blocks in the satellite. Covering 27 to 31 GHz, the DS1017 has a maximum insertion loss of 0.6 dB, minimum isolation of 20 dB and return loss of 20 dB or better in a 50 ohm system. RF leakage is rated at -70 dBi. The isolator will handle up to 5 watts of forward power and 30 watts peak. Without connectors, the DS1017 measures 0.5" × 0.7" × 0.5" and weighs 20 g. The isolator is interconnected with 2.92 mm female connectors.

DiTom can deliver the DS1017 isolator six to eight weeks following customer order – even sooner depending upon customer test requirements. This is significantly faster than space-qualified components from other suppliers.

DiTom Microwave designs and manufactures high quality, connectorized ferrite isolators and circulators for space and defense and is AS9100 Rev. C certified. The company offers both commercial off-the-shelf and high reliability from 400 MHz to 40 GHz.
